Production of heat during plasma electrolysis in liquid

Plasma was formed on the surface of an electrode in a liquid solution when metal cathodes underwent high-voltage electrolysis. A red-time heat calibra tion system was designed for detecting the amount of heat generated during plasma electrolysis. The measured heat exceeded the input power substantial ly, and in some cases 200% of the input power. The heat generation process depended on the conditions for electrolysis. There was no excess heat at th e beginning of plasma electrolysis. However, after plasma electrolysis for a long time, a large amount of heat was generated. The reproducibility woul d be 100% if all factors such as temperature, voltage and duration were opt imized. Based on the heat and the products, we hypothesize that some unique reaction occurs on the cathode surface. This reaction may not occur at ene rgy levels available during electrochemical electrolysis.
